Abstract

We investigate the emergence of hyperons in black-hole-forming failed supernovae, which are caused by the dynamical collapse of nonrotating massive stars. Attractive and repulsive cases are examined for the potential of Σ hyperons to find that it affects the accompanied neutrino emission through the core-collapse dynamics. The neutrino duration time during black hole formation for the repulsive case is ∼15% longer than that for the attractive case.
